Dropping the top

Because only a small portion of the "roof" of the vehicle covers the passenger compartment (and because the V12 engine sits where most vehicles would stow a retractable roof, Lamborghini has chosen to use a two-piece carbon fiber roof that must be removed by hand and stowed in the storage space beneath the Aventador's hood.

Spinal column

Where the Aventador coupe displays its V12 engine beneath a large, louvered glass window, the Roadster adds a metal "spinal column" to add back the chassis rigidity lost by removing the roof. The engine is still viewable through a pair of hexagonal openings.

Finishing touches

Azzuro Thetis, new, metallic blue color, has been added to the Aventador's range of colors--although, I prefer the matte black that the coupe is often seen wearing. A new style of wheel also debuts on the Roadster.
